Silicone bag with seal

ABSTRACT

A bag having a front and back portion which are comprised of silicone or a similar elastomer. The front and back portion are identical in size and are sealed together along their sides and bottom with an opening along the top portion. The opening creates a cavity from which items are placed in and stored or transported for further use. A sealing mechanism on top of the bag seals items in the bag. The bag is water tight.

FIELD OF THE INVENTION

The present invention relates to a silicone bag having a seal.

BACKGROUND OF THE INVENTION

In the past, plastic bags have been used for transporting foods and liquids. These bags cannot be used for heating. Further these bags cannot be used in a microwave oven. Also, plastic bags are not reusable. Further, many of the plastic bags use potentially toxic chemicals.

Another way for transporting and storing food stuff is by plastic containers. These containers also contain harmful chemicals. These containers are bulky and take up a lot of room.

U.S. Pat. No. 4,842,670 relates to a method for forming silicone rubber vacuum bag assemblies which can be used repeatedly to debulk and autoclave composite layups. These bags can be formed of a single layup of uncured silicone rubber over a tool of a simple shape or as a layup of uncured silicone rubber over the totality of the tool and a prepreg consisting of a fiber in uncured silicone rubber laid up over areas which do not include male and female radii on the tool.

U.S. Pat. No. 5,665,301 relates to a unitary vacuum bag for forming of a fiber reinforced composite article, made of a fabric mesh reinforced curable elastomer, having a smooth surface on both sides. The bag is constructed upon the surface of the article which is to be reproduced and upon a planar flange extension of the mold for the article.

U.S. Pat. No. 5,686,304 relates to a cell culture apparatus formed of a plurality of thin spaced, gas-permeable, silicone membranes sealed at their edges to form a bag-like vessel comprising one or more interior chambers suitable for containing cell culture media.

U.S. Pat. No. 6,632,164 relates to an apparatus for forming a bag assembly from a tube and a tubular flexible membrane operating in accordance with a four step process. The process includes clamping the tube within an open end of the membrane, injecting liquid adhesive into the open end of the membrane, clamping the membrane and rue where the adhesive was injected, and heating and curing the assembly.

US patent publication 2006/0083833 relates to a flexible foodstuff mold for use in confectionary, bread making or baking, wherein the mold comprises a base, wall extending from the base, and a rim projecting from the wall. The mold includes at least two or more handles and a rigid rim area at the vicinity of each handle, other areas of the rim being flexible.

US patent publication 2010/0218690 relates to a utensil for containing foodstuff, applicable to cooking in a microwave, including a receptacle made of an elastomer material with an access opening and a cover for covering the access opening. The receptacle has one or more walls including a bottom wall in elongated channel shape and opening edges defining access opening at a height greater than the bottom. The bottom wall has reinforcing ribs. The bottom wall is connected at its ends to end walls.

US patent publication 2012/0037618 relates to a kitchen container made of a flexible material such as a silicone elastomer, and it has the shape of a bowl with a base, a perimetric wall and a perimetric rim that form an upper opening. The wall is flexible enough to allow first and second opposite sides to be bent towards each other and have fastening elements to fasten the sides so that they overlap each other, and the rim forms two opposite openings separated by the overlapping portions. It can be used to cook in a microwave or conventional oven.

US patent publication 2011/0038564 relates to a reusable bag which is resealable by means of a top press and seal strip or strips, so that food stuffs or other items can be transported or stored in a sanitary condition. The bag may be composed entirely or in part of silicone so that it is durable, recyclable, impermeable to liquids and can withstand extremes of temperature making it suitable for freezing or thawing as well as transporting foods. The bag may be transparent, opaque or have artistic designs or measurements incorporated into its manufacturing.
